Better reviewing when fsiled
The main problems I have with reviewing a kanji is that if I forget what the kanji looks like and therefore fail, it immediately goes to the step with the green dots where it feels like it's wasting my time. I already know where the start points are, and you either have to do that just to eventually do it without any guide on screen or mark it as "just learned" to skip it to the next day. Maybe it could be a toggle in the settings that it doesn't immediately go back to the one with the green dots, if after seeing it when failing that you fail it again then go to the green dots. Since the issue may not be getting the wrong order, start points, etc but just need to see the kanji again as you already know where the start points are and the stroke order.
Also, would be nice if there was a way to have more personalised reviews for each kanji since you may struggle a particular part of a kanji and not the whole thing, for example with not knowing the right side of a kanji while knowing the left side of 読. Or maybe with certain parts of kanji, like with remembering if it's 宀 or 冖, or the stroke order when it comes to overlapping vertical and horizontal lines.
